WHISTLE.

Application filed March 7, 1925; Serial No. "13,845.

This invention relates to whistles and moreparticularly to the :constructionof a. locomotive whistle.

An important object of the invention is to'providea whistle. which may bearranged to have-a distinctive note .or collection or" notesso that it may be readily recognized. It is well known that engineers particularly of locomotives like to have a whistle attachedto their engine which is clearly -dis tinctive and which will be readily recognized byv persons hearing the :same.

A still further :object'ot the invention is to provide a whistle construction such that the note or combination of notes produced by the whistle may be altered at will and in which the =-arrangement permitting such changing of-the whistle note is simply and readily operated.

A still further object of the invention is 1 -to provide a device o't this. character which 'may be relatively cheaply produced and installed and which, as a matterjot fact, may be substituted for the ordinary whistle bell .now employed on the whistles of locomotives. I v

These and other objects we attain by the construction shown in the accompanying drawings, wherein 'torthe purpose of illustration is shown apreterred embodiment of our invention and wherein Figure 1 1s aside elevation of a whistle constructed in accordancew1th our invention; v

Figure ,9 is f Figure- 8. i

"Referring nowFmore particularly to the drawing that form of construction shown f in Figuresl to 5 thenumeral 1O designates a sectionon theline '9-9 of a standard whistle ba'sewhich, asiis Well known to those .tamiliar'with the. art,-' includes an oiuter shell 11, a spider support 12 arranged withinythe shell, a disk 13 -.supported by the spider and having its periphproximity to the inner pe- 2' i ery extended into riphery of the. shell-but spaced therefrom to provide a steam exhaust slot 1. 11 and a flange .15 controlling the passage of steam to and through the slot. *Thespi-der 12 has a central threaded bore 16 for the reception disk .13 in position and preventing movement of the post. This structure formsla normal part of the whistle structure and does not enter into the invention except as hereinafter described. i

Inac'cor'dance with our'invention, we pro video a body having a central bore 20 through which thepost 17 extends. In the form of invention now under discussion, this boreis formed by providing a central tube 21. The nut 19 has between faucets thereof,

rounded portions 22 fitting the lower inner end of the tube to hold the same concentrically with the post 17. The upper end of this tube-21 has a cap 23, the sideedgeso'f which. project to provide .a flange 24,the

purpose of which will .presently'appear. This cap has a central opening 25 through which the threaded upper end26 of the post may extend. Upon the'post 17 is mounted a roundnut 28 fitting the interior of the:-

tube and abutting the under surface of the cap- Above the upper surface of the .cap,

.the post hasmounted thereonan ornamental lock. nut 29 for securing the cap in position against the nut 28. By adjusting the nut 28.,

vertically. upon. the post 17 the position of this central tube'and allparts carried thereby,fhereinatterto' be more fully described,

may be adjusted.

'Surrounding'the tube'21 are a plurality of whistle tubes .or bells 30. "These being similar, the description of one will herein sufiice. Each tube "has {a closed upper end 81 having extending upwardly therefrom a tubular stem guide 32, the upper end of which is split, as 211333, and the exterior of i I which is tapered and exteriorly screwthreaded, as at 34:. Coacting' with this stem guide is alocking band 35 which, when screwed down upon the guide, will compress tubes.

. form of the device,

the upper end thereof to bind the same againstthe stem 36 of a piston 37 operating withinthe tube and fitting the same. The upperendof this rod has a handle 38 in the form of an ornamental cap by means of which it may be adjusted. When a proper adjustment of the piston 37 is had, it may be locked in position by tightening the ring 35' so that the, guide clamps against the rot 36." The piston 37 is preferably provided with a packing ring 88" as illustrated.

In its formation, the lower end of each tube is split and the ends thereof spread, as indicated at 39. The separated tube sections of adjacent tubes are secured to one another as by welding or brazing at 40 and provide radially extending points below the space between adjacent These baffles serve to prevent steam passing from theslot 14 from spreading out and concentrate it upon the lower ends of the tubes. The tubes 30 may be secured to the tube 31 by spotwelding, as indicated at 42, and 'may have their upper end walls secured to the projecting flange 24 of the to p the bell formed by the 'combinatlon of tubes is placed in position upon the whistle base and the pistons 37 adjusted until a desired tone is produced after which they are locked in position. If itis desired to cha'nge the pitch of the tone, the entire assembly is vertically adjusted by vertically adjusting the nut 28 as hereinbefore suggested.

In the form shown in Figures 6 to 7 the samestructure is produced but is'produced integrally by a casting from any moldable metal. At the same time, certain changes are made in the adjustments provided as will hereinafter become obvious. The wall of the bore 20 is provided at its lower end with interior threads, indicated at 43. The

,nut 19 is replaced by a nut 44 having a depending sleeve 45 interiorly fitting and V threaded into the bore 20, the lower end of this sleeve abutting the plate 13 to hold the same 1n position. The post employed is substantially the same with the exception of the fact that the nut 28 is not employed ythereon', the post extending through an opening 15 of the upper end wall 46 of the structure. The lock nut 29 is provided and an adjustment of this type, as a whole, is

had by loosening this lock nut and then bodily rotating the bell until the desired height of adjustment is had after which the lock nut 29 is firmly seated against the If desired, the manner of adjusting the pistons 37 mav be modified as suggested in F1gures8 and 9. In these figures, We have 7 shown the cylinder 30 as provided with a longitudinally extending groove 50 in the Walls thereof and the piston 37 as provided baffles 41 occupying the 23 of the tube 21. In the use'of this with a lug 51 'engagingin this groove to prevent rotation of the piston. The stem of the piston, indicated at 36 is threaded through the piston so that by rotation of this stem, the piston may be adjusted longitudinally of the cylinder. Any suitable means may be provided for locking the stem against rotation. In the present illustrasiderable range of change and modification without materially departing from the spirit of our invention and we accordingly do not limit ourselves to such specific structure except as hereinafter claimed.

WVe claim 1. In a whistle, a whistle each of said tubes, includingpistons mov-' able within each tube and having stems probase, a standard 1 extending upwardly therefrom, a bell vertijecting through guides carried by the tube,

j 4. In a whistle, a whistle base, a standard extending upwardly therefrom, a sleeve supported from the standard, the bell including a structure having an axial bore surrounding the standard, said bore having threads for coaction with threads formed upon said sleeve and thereby affording means for vertically adjusting the bell upon the standard and a locking nut carried by the standard.

for preventing rotation of the pistons, means ,for adjusting the pistons longitudinally of piston adj ustable, therein, means the bell tubes and meansfor locking the pistons in adjusted position.

6. In a Whistle, a Whistle base, a standard extending upwardly therefrom, a bell vertically adjustable upon the standard, a piston adjustable in the bell, means for locking the bell in adjusted positions, 7 means for locking the piston in adjusted positions, said piston being held against rotation with relation to the bell, a rotatably mounted stem for the piston and havingthreaded engage? ment With the piston and means for locking the piston stern against rotation.
